Abstract
An injection pinhead which maintains the thin wall tubular pin body and the pinhead seat of the prior pin changes the pin into a pyramid shape. The root part of the pyramid groove is opened with a liquid medicine via hole. The edge of the liquid medicine via hole near to the outer surface of the pin body has a transition arc surface. The pinhead conquers the existing phenomenon of cutting off the skin and flesh of the prior pinhead, reduces the infected opportunity of the pin hole, puts an end to the hidden trouble of injecting solid organization into the vein.
Description
This utility model belongs to technical field of medical instruments.
The needle point of the syringe needle of existing injection all is to wear into an inclined-plane and constitute in the preceding end-grain cutting of the needle body of thin light-wall pipe.The needle point of this form is because the inwall and the inclined-plane of needle point latter half still constitutes sharp sword, can cut off the skin and flesh tissue of process.Therefore, existing injection syringe needle all cuts away in the straight skin and flesh tissue and input body through being equivalent to the syringe needle endoporus in use.This phenomenon.Though do not noted for many years, and do not mean that and be safe from harm by people.For intramuscular injection, the injection site will stay micropore after the withdraw of the needle, and infection and hemorrhage probability are well imagined.If the blood vessel drug delivery also exists fritter skin and flesh input blood vessel, can not say definitive there not being hidden danger.
The objective of the invention is to change the shape of injection needle needle point, make it when thrusting human body, can not downcut skin and flesh, to overcome the above-mentioned deficiency of prior art.
The technical solution of the utility model is to keep the tubulose needle body of existing syringe needle and push away pencil or needle holder that infusion tube matches, and improved part is that needle point is squeezed into pyramidal shape, and has liquid through-hole at the root of pyramidal each groove.Liquid through-hole has the transition circle cambered surface near the edge and the needle body outer surface of needle body outer surface.
Using good effect of the present utility model is syringe needle when thrusting human body, by pyramidal needle point skin and flesh is strutted gradually, does not have and cuts away part, thereby avoided the solid content intravasation, and pin hole is closed fully after the withdraw of the needle, has reduced chance hemorrhage and that infect greatly.
Accompanying drawing 1 is contained in the overall schematic that pushes away the syringe needle on the pencil in this utility model.
Accompanying drawing 2 is a needle point direction view of the present utility model.
Embodiment: material and technology with prior art are made tubulose needle body 1, with push away the needle holder 2 that pencil or infusion tube match, then the needle body front end is extruded into the rhizoma sparganic taper, be equipped with liquid through-hole 3 at pyramidal root of notch, liquid through-hole 3 has the transition circle cambered surface near the edge and the needle body outer surface of needle body outer surface.
Claims (1)
- A kind of injection needle comprises tubulose needle body (1), and needle holder (2) is characterized in that needle point is a pyramid-shaped, has liquid through-hole (3) at pyramidal root of notch.
